Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461834, here are decompositions:

11 + 31461823 = 31461834
17 + 31461817 = 31461834
23 + 31461811 = 31461834
43 + 31461791 = 31461834
71 + 31461763 = 31461834
73 + 31461761 = 31461834
97 + 31461737 = 31461834
137 + 31461697 = 31461834

Showing the first eight; more decompositions exist.
